Ground fault circuit interrupters are therefore stipu-
lated for the electrical installation of AHT cabinets in
stores. It is deemed practical that the AHT cabinets
have their own ground fault circuit interrupter protec-
tion for the lighting.
When using ground fault circuit interrupters, it is im-
portant to ensure that the circuit interrupters being
used are type “G” (surge current resistant). In order to
enhance the performance of the ground fault circuit
interrupter, we suggest the following:
Nominal current 40 A
Trip current 30 mA
Trip characteristic C
Cabinets for each ground fault max. 2
It is preferable for each cabinet to have 1 ground fault
circuit interrupter for individually protecting the cabi-
nets. With a combination of a fuse and circuit break-
er (ground fault circuit interrupter/miniature circuit
breaker), a maximum of 2 cabinets are supplied for
each circuit protection.
note
• No more than 2 cabinets should ever be connected
to a ground fault circuit interrupter (GB/USA: RCCB)
or a ground fault circuit interrupter/miniature circuit
breaker combination (GB/USA: RCBO).
6.2.3 Ground fault circuit interrupter/
miniature circuit breaker combination
(RCBO)
The following types of ground fault circuit interrupter/
miniature circuit breaker combinations can be used for
1 or 2 cabinets:
Quantity Cabinet 1 2
Characteristic “C“ “C“
Nominal current 10 A 16 A
Trip current 30 mA 30 mA
Type “G“ “G“
notes
• AHT however recommends a ground fault circuit in-
terrupter/miniature circuit breaker combination for
each cabinet.
• Load shedding circuits or cabinet circuits are not per-
mitted as interferences may occur
• In the case of cabinets with an integrated internal
light and separate light connection cable, each cabi-
net must have an additional light socket. A maxi-
mum of 8 light connection cables may be connected
to a single fuse.
7. Commissioning and
function
The cabinet should have a minimum temperature of
+16 °C (60.8 °F) before being commissioned.
All cabinets are equipped with a glass or insulating
lid as standard. These lids are required to operate the
cabinets correctly.
Lid variants:
- Sliding glass lid
- Insulating lid
- Hinged glass lid (for Sao Paulo H 135 and Sao Paulo
H 175)
CAUTION
Risk of injury when closing the hinged
glass lid.
Hands could become trapped.
➤ Let go of the hinged glass lid before it
closes.
➤ Do not rest hands on the cover frame.
note – applies to all lid variants
• The cabinet must only be operated with the lid
closed. Otherwise, the cooling surfaces could ice
up. If this happens, the required temperatures can-
not be maintained.
➤ No objects should be trapped between the glass
lid and the cover frame.
➤ The lids may only be opened briefly for the stor-
ing and removal of products. Afterwards, it must
be completely closed again.
The bulging that may occur during operation does not
have a negative impact on how the cabinets function.
Important information for handling D-Ice cabi-
nets:
In order to precisely maintain the temperature distribu-
tion required, the cabinet is equipped with an internal
fan, which is located in a stainless steel housing. The
basic equipment of the cabinet includes hanging bas-
kets, in which the ice containers are placed. The two
outer hanging baskets are equipped with wall spacers.
